Internet Speed Test

Welcome to the SourceForge Speed Test. This speed test is uniquely designed to test your current Internet connection speed for Latency/Ping, Jitter, Download Speed, Upload Speed, Buffer Bloat, and Packet Loss. Upon completion, you will be notified as to what types of services your connection is capable of handling, as well as additional reports about your connection. This HTML5 speed test does not require Flash or Java, and works on all devices including tablets and smartphones. Please click the 'Test Now' button below to begin the test! This test utilizes WebSockets for latency, jitter, and buffer bloat measurements. For best results close out other open tabs in your browser and ensure your computer is mostly idle.

What does this HTML5 speed test do?

This speed test will test your Internet connection speed, including a significant amount of additional information such as latency/ping, jitter, download speed, upload speed, buffer bloat, and packet loss, in order to provide you a detailed report on what type of services your connection can support. These services include VoIP (voice over IP), live video streaming such as YouTube or Netflix, gaming, and more. Unlike most speed tests, the SourceForge speed test does not require Flash or Java, and instead uses more universally compatible HTML5, which allows the test to run on all devices including tablets or smartphones.

What do my test results mean?

After running the speed test, you will be presented with a number of results in different formats. But what do these numbers mean? Here is a brief explanation as to what your test results mean in relation to your current broadband connection:

1 Latency/Ping: the measurement of the time it takes a single packet to be sent from your computer to a remote computer and then back.

2 Jitter: the measurement of consecutive latency test results. Your ideal jitter result is as close to zero as possible.

3 Download Speed: less a measurement of speed, this is how many bits per second can be downloaded from one computer to another via the Internet.

4 Upload Speed: less a measurement of speed, this is how many bits per second can be uploaded from one computer to another via the Internet.

5 Buffer Bloat: a measure of latency, it is a test performed when your connection is under stress. This is usually achieved by running a bandwidth test to maximize your connection.

6 Packet Loss: the measurement of how many data packets arrive at their intended destination when sent from a computer. Ideal packet loss is zero percent.
